Abstract:
ABSTRACTThe purpose of this paper is to report a clinically induced phonemic split (i.e., the restructuring of allophones as distinct phonemes) by presenting longitudinal data from a functionally misarticulating child. For this child, three qualitatively and quantitatively distinct stages were observed relative to the acquisition of the phonemic split: 1. complementary distribution (allophones of the same phoneme); 2. position-specific free variation (intermediate to a phonemic split); and 3. phonemic distinction for some, but not all morphemes (phonemic split).The results of this clinical case study, documenting the nature and development of a phonemic split, have implications for related phenomena in normal language acquisition, second-language learning, and sound change in primary languages.

Abstract:
The phonological analysis of phonemes as segments including consonants and their allophones, consonant clusters, and vowels with their allophones that may work in complementary distribution or in free variation with each other are tackled in this paper beside sounds in context to show how sounds produced in rapid connected speech reveal affection to each other producing utterances colored by assimilation, elision, and intrusion. The paper aims to show the different sub-types of these phonological processes such as coalescent assimilation, syncopic elision, and epenthetic intrusion. The paper is a reprint of an edited chapter of an M.A. thesis entitled '' A Phonological Analysis of Segmental Phonemes in Standard English and Hit Iraqi Arabic '' to be presented in confirming with the requirements for an M.A. degree.

Abstract:
The velar nasal, also called "Engma" or "Angma", can be found in the phonologicalinventories of many languages across the world. Kurdish researchers vary in their opinions as to whether this sound is listed among the inventory of Kurdish language phonemes or not. Some researchers have tackled this case in Sorani Kurdish but research in Badini is scarce in this area. In this paper we aim to investigate the velar nasal /N/ in Badini Kurdish, which is a very controversial topic. The paperaims to answer the question as to whether it can be considered as a phoneme or it is just an allophonic realization of the alveolar nasal /n/ when followed by the voiced velar stop/g/. This is done through providing examples that have the combination of (n+g) which have a possible occurrence of the velar nasal. These examples are first analyzed articulatory in terms of some phonological processes such as assimilation, morpheme affixation, and syllabification. They are then analyzed acoustically by contrasting the pairs and searching for nasal bands using Praat. After analyzing both articulatory and acoustic data, it was concluded that the velar nasal can be found in Badini Kurdish but only as an allophone of the alveolar nasal which is the result of certain phonological rules such as assimilation and co-articulation. They are in free variation and couldn’t change the meaning. So, we can’t consider it as a distinct phoneme in this dialect.

Abstract:
This paper attempts to account for the velar affrication in Najdi Arabic (NA) and its absence in Hijazi Arabic (HA). While NA consistently alters /k/ into [ts], and /ɡ/ into [dz], HA retains the velars and as such is more faithful to standard Arabic. The analysis follows from an Optimality-Theoretic (OT) framework (Prince and Smolensky, 1993) explicating different constraint interactions and introducing new markedness constraints. It is argued that the realizations of the velars as [k] and [ɡ] are in free variation distribution with their allophonic affricate counterparts [ts] and [dz], respectively, although the two variants of the same phoneme alternate under phonologically conditioned contexts.

Full text
Abstract:
Most discussions of the Korean liquid phoneme /l/ identify two allophones: a flap, [ɾ], in the onset of syllables, and an alveolar lateral approximant syllable-finally and in geminates. However, some research paints a more complex picture indicating a wide range of interspeaker variation for the precise articulatory realization of these allophones. The present research finds that in regards to the tap and laterals realizations previous descriptions are largely correct. It also affirms through analysis of F2 values that previous findings showing that the Korean lateral is palatalized before high front vocoids are correct. Most importantly, it analyzes F3 values to show that the retroflex variant is particularly prevalent near pauses, suggesting that retroflexion may be a secondary cue to prosodic boundaries.

Abstract:
Abstract This paper presents the first sociophonetic study of Cantonese vowels using sociolinguistic interview data from the Heritage Language Variation and Change in Toronto Corpus. It focuses on four allophones [iː], [ɪk/ɪŋ], [uː], and [ʊk/ʊŋ] of two contrastive vowels /iː/ and /uː/ across two generations of speakers. The F1 and F2 of 30 vowel tokens were analyzed for these four allophones from each of 20 speakers (N = 600 vowel tokens). Results show inter-generational maintenance of allophonic conditioning for /iː/ and /uː/ as well as an interaction between generation and sex such that second-generation female speakers have the most retracted variants of [ɪk/ɪŋ] and the most fronted variants of [iː]. This paper will discuss three possible explanations based on internal motivation, phonetic assimilation, and phonological influence. This will illustrate the importance of multiple comparisons (including inter-generational, cross-linguistic, and cross-community) in the relatively new field of heritage language phonology research.

Abstract:
The aim of the present study involving automatic phonetic classification of /e/ and /u/ tokens in Tol is two-fold: first, I test existing claims about allophonic variation within these vowel classes, and second, I investigate allophonic variation within these vowel classes that has yet to be documented. The acoustic phonetic classifications derived in the present study contribute to a more detailed understanding of the allophonic systems operating within the Tol language. Operationalizing machine learning algorithms to investigate under-resourced, indigenous languages has the potential to provide detailed insights into the acoustic phonetic dynamics of a diverse range of vocalic systems.

In the phonology and morphophonology of Limbu (Tibeto-Burman, Nepal), we find what could be considered as rules of voicing (of stops) and gemination (of stops and nasals). The interpretation of these phenomena leads us to assign an independent role to the syllable boundary as part of the phonological environment conditioning the distribution of allophones.

<p class="1">How do speakers reconstruct the boundaries of an allophonic system? In our paper, we address this question and examine how speakers organize into consistent groups of allophones the array of /r/-variants that are used in South-Tyrol Italian (STI). In addition, we discuss that this process of grouping is based on two intertwining sources of variation: the linguistic source and the socio-indexical source. We argue that the indexical dimension is not disconnected from the linguistic one, but it contributes in an essential way to its structuring.</p><p class="1">Our investigation is based on a sample of two thousand tokens of /r/. These occurrences are extracted from a corpus that includes the (semi)spontaneous productions of 14 Italian-German bilingual speakers. The analysis concerns the identification of possible relationships among the allophones with respect to (a) distributional, (b) stylistic and (c) biographical factors. Data are analyzed using a multivariate exploratory technique, namely the multiple correspondence analysis approach. The results clearly show how the aggregation of indexical and linguistic factors determines the emergence of two different allophonic subsystems, that is the Italian of Italian-dominant speakers (STI-i) and the Italian of German-dominant speakers (STI-d).</p>

Abstract:
Glottal stop is a widely reported phenomenon in the United Kingdom, but it has been rarely studied in the United States. The current study follows up on work on this feature in a wide age range of speakers in Vermont. Currently the speakers comprise thirty-six children ages 2;6 to 5 from this same location. In addition to demonstrating that these children have acquired the phonological constraints, as well as the full range of allophones of /t/, the results provide a lens through which to explore other issues of language acquisition and language variation, most notably, the boundary between dialectal and developmental variation. In general, it is argued that sociolinguistically conditioned variation adds empirical as well as theoretical value to studies of phonetically and phonologically conditioned variation and acquisition of the phonological system by first language learners.

Abstract:
AbstractPrevious studies of language contact in multilingual urban neighborhoods in Europe claim the emergence of new varieties spoken by immigrant-background youth. This paper examines the sociolinguistic conditioning of variation in allophones of Swedish /ε:/ of young people of immigrant and nonimmigrant background in Stockholm and Gothenburg. Although speaker background and sex condition the variation, their effects differ in each city. In Stockholm there are no significant social differences and the allophonic difference appears to have been neutralized. Gothenburg speakers are divided into three groups, based on speaker origin and sex, each of which orients toward different norms. Our conclusions appeal to dialectal diffusion and the desire to mark ethnic identity in a diverse sociolinguistic context. These results demonstrate that not only language contact but also dialect change should be considered together when investigating language variation in modern-day cities.

Abstract:
ABSTRACTThe phonological acquisition of a young girl whose parents spoke two dialects of Cantonese was examined. The father's dialect had a phonological distinction between initial /l/ and /n/ which was merged into /l/ in the mother's dialect. The child was followed bi-weekly for approximately one year. The results indicate that she acquired neither the mother's nor the father's dialect. Instead, she acquired [l] and [n] as freely varying allophones of a single phoneme. In the first months, [n] was the most frequent realization of the phoneme, with [l] becoming the most frequent one in later sessions. The results are interpreted as supporting the claim that children use all available input in acquiring language rather than limiting themselves to a primary language model.

Abstract:
Most handbooks and grammars contend that in Old English the voiced fricatives [v, ð, z] were merely allophones of /f, θ, s/ in sonorous environments. How these voiced fricatives became phonemes is debated among scholars. In this article, all previous accounts are critically reviewed. A new proposal is then presented, which explains the facts in a more direct way than previous theses. I argue that phonemicisation of a previous allophonic voice alternation in fricatives had already taken place in many areas of Anglo-Saxon England through language contact with Brittonic. Voiceless as well as voiced fricative phonemes existed in Brittonic at the time of contact, and language shift would have led directly to the phonemicisation of the previous allophonic variation found in early Old English.

<p>The current work tackled two phonemes, /k/ and /g/, examining the phonological operations in charge of their allophonic variation in Ha’ili Arabic. The study found out that the phoneme /k/ has two allophones: [k] and the dental voiceless affricate [ts]. The latter occurs when preceded or followed by either [a] or [i], whilst the former shows up elsewhere. However, the latter generalisation falls out when the resulting allophone violates the Obligatory Contour Principle (OCP) which impinges on the occurrence of the allophone affricate [ts] when clustered with sounds with same place features. Similarly, the study argued that the phone /g/ has two surface forms whose occurrence is predictable: [g] and the voiced dental affricate [dz]. The latter shows up when preceded or followed by the front high vowel [i], whereas the former occurs elsewhere. Additionally, the study worked out how affrication feeds vowel lowering in HA. </p>

Abstract:
AbstractMontrealers are often categorized into three distinct groups: Anglophones, Francophones, and Allophones. However, within these groups there are individuals whose trajectories are complex, as reflected, for example, in their linguistic practices. Our interest lies in the relationship between these complex practices and the ethnolin-guistic attributions of the speakers. We concentrate on two groups of Francophones: those from Spanish-speaking families who have been in Quebec for one or two generations and those from Francophone families who have frequent English-speaking contacts. After summarizing the results of a perception test, in which Francophones from Quebec were asked to identify the ethnolinguistic affiliation of speakers of various origins based on short clips of their French, we analyze the usage of sociopho-netic variables reflecting the influence of French, Spanish, or English. The analysis indicates that phonetic variation stems from speakers’ sociosymbolic orientation, as well as certain other sociodemographic factors linked to identity construction as it relates to ethnicity.

ABSTRACT In this study, 30 strains of the pathogenic free-living amoebaNaegleria fowleri were investigated by using the randomly amplified polymorphic DNA (RAPD) method. The present study confirmed our previous finding that RAPD variation is not correlated with geographical origin. In particular, Mexican strains belong to the variant previously detected in Asia, Europe, and the United States. In France, surprisingly, strains from Cattenom gave RAPD patterns identical to those of the Japanese strains. In addition, all of these strains, together with an additional French strain from Chooz, exhibited similarities to South Pacific strains. The results also confirmed the presence of numerous variants in Europe, whereas only two variants were detected in the United States. The two variants found in the United States were different from the South Pacific variants. These findings do not support the previous hypothesis concerning the origin and modes of dispersal of N. fowleri.

Abstract:
The acoustic study of consonants has lagged considerably behind that of vowels. While a robust literature exists about vowel shifting, vowel quality, and the sociolinguistic significance of vowels, comparable literature is lacking for the acoustic quality of liquids. This study seeks to supplement the acoustic studies of vowels by analyzing characteristics of the liquid /l/ in its word-initial context. Traditionally, phonologists have subdivided /l/ into two allophones: dark and light, although current analysis has characterized these distinctions as gradient, not discrete. Word-initial /l/ is thought to be the canonically lightest variant of the phoneme, but cross-dialectal research has shown great acoustic variance in its phonetic realization. This case study aims to trace the phoneme through three generations of Chicano English speakers from South Texas, and to draw conclusions about how its variation among speakers and generations can shed light on other sociolinguistic phenomena, such as the persistence of substrate features from Spanish (with its characteristically light /l/s) or assimilation into mainstream American English dialects (with their characteristically dark /l/s). The study shows that there is indeed significant shift in the lightness of /l/ — independent of phonetic context — across the generations of speakers under examination. This result supports other studies that show notable assimilation with Anglo English varieties in earlier generations, but robust use of ethnically-marked phonological features among recent generations.

Abstract:
It is well known that the concept of energy has played a fruitful role in potential theory and Markov processes. Cartan’s work [6] led to kernel-free potential theories of Beurling-Deny [2]. Since then many authors have worked on this, M. Fukushima [8], M. Silverstein [16], J. Bliedner [3], Berg-Forst [1], to name some. In these works, however, the main thrust is Hubert space theoretic.
